testing heater valve?
82 380sl with solenoid heater valve.
any way of testing this valve to see if it works
put a new replacement mon valve replacement in the valve but it still blows hot air all the time.
put 12 v on contacts and they did click but nothing appeared to move.
should you be able to see the valve move up and down from the top of the valve( the round cylinder on top of the valve)?
